9 is your answer
because 10times35 is 350 -35 is 315
Answer:
I think the answer is Option D, 135 degrees.
Since the angles of all of the octagon combined is 1080, divide that by 8 to get 135 which means that all 8 angles are 135 degrees.
Okay, so basically we have:
w as width; and 6+w as length
Perimeter=2w+2l
just substitute it with the values of width and length
P=2w+2(6+w)
P=2w+12+2w
P=4w+12
So, the answer is letter B.
2x-5=25
Add 5 to both sides
2x-5+5=25+5
2x=30
Now, divide both sides to find x
2x/2=30/2
x=15

To find Tasha's age, subtract 25 and 15
Therefore, Tasha is 10 years old
